Provides classes and interfaces for creating an index that handles numeric
data. The {@link com.bbn.parliament.jena.graph.index.numeric.NumericIndex}
indexes a specific predicate and number type using the Berkeley DB Java
Edition. The <code>NumericIndex</code> and {@link
com.bbn.parliament.jena.graph.index.numeric.NumericIndexFactory} classes
are abstract. Concrete implementations are provided as static nested
classes. For instance, {@link
com.bbn.parliament.jena.graph.index.numeric.NumericIndex.DoubleIndex}
and the related {@link
com.bbn.parliament.jena.graph.index.numeric.NumericIndexFactory.DoubleIndexFactory}
provide an index and factory for {@link java.lang.Double}s.
<p />
The {@link com.bbn.parliament.jena.graph.index.numeric.NumericIndexPatternQuerier}
claims triples of the form <code>?s &lt;predicate-to-index&gt; ?o</code>.
The index is intended to be accessed only for range queries.
